r�1 <br /> I. INTRODUCTION <br /> This report issues our findings regarding the Nitrate Loading Study and Soil Suitability Study for <br /> the proposed Eagal Lake Recreation Complex. Mr. John Eagal is the owner of the project and <br /> has provided the preliminary information to complete these studies. The Site Plan was provided <br /> }, by Sanguinetti &Associates - Consulting Civil Engineers of Stockton, CA. <br /> The San Joaquin County Environmental Health Department(PHS-EHD)requires Nitrate <br />` Loading and Soil Suitability Studies for projects in unsewered areas, or for projects which may <br /> potentially impact the underlying groundwater with nitrate. This report complies with the San <br /> Joaquin County Development Title, Section 9-1105.2 for a Nitrate Loading Study and Soil <br /> Suitability Study. Additionally, this proposed project should comply with the Environmental <br /> Health Department Sewage Standards, specifically Section 10 - "Requirements for Waste <br /> Disposal for New Land Developments." <br /> The primary concern of nitrate in drinking water is that high concentrations can cause <br /> methemoglobinemia in infants and it can also induce abortion or death in cattle. This disease <br /> occurs through a series of complex chemical reactions within the hemoglobin in the blood. Only <br /> infants and young children are susceptible. Although this disease is extremely rare, nitrate can <br /> also potentially cause other health concerns. There have been scientific studies to suggest that <br /> nitrate may produce carcinogenic effects in humans. i <br /> Nitrate concentrations in water can be expressed in two different terms: 1.) as the weight of the <br /> nitrate molecule, which is one atom of nitrogen and three atoms of oxygen for an atomic weight <br /> of 62 units. Or, 2.)nitrate can be expressed as the amount of the nitrogen atom itself. This one <br /> atom of nitrogen (N) in a nitrate molecule contributes 14 atomic weight units to the weight of the <br /> nitrate molecule. The ratio of weight of the nitrate molecule (NO,) to the atom (N) is 62114 or <br /> approximately 4.5. The U.S.E.P.A. has established the Maximum Contaminant Level (MCL) of <br /> nitrate in drinking water at 45 mg/l as nitrate. Due to the ratio described above, the MCL is <br /> sometimes reported as 10 mg/l as nitrate-nitrogen. <br /> The project site is located on a private road 1800 ft east of the terminus of Lorenzen Road and <br /> P J <br /> is adjacent to the San Joaquin River. The Duel Vocational Institute is located to the northwest <br /> and the City of Tracy is to the west. <br /> � 6040, <br /> r <br /> The project consists of two Parcels, APNs 239-140-03 and 06, with the description as follows: <br /> Parcel 1 is composed of 49 acres and includes an existing 13-acre lake which will be used for <br /> fishing, an existing riparian area, constructed trails and picnic areas. Parcel 2 is located adjacent <br /> to, and directly north of Parcel 1. Parcel 2 will include a proposed 13.6 acre lake that will be part <br /> of a private ski club, riparian areas, a proposed 4,000 sq ft dry storage building and a 3,000 sq ft <br /> Ski Shop. Parcel 2 is bound by the San Joaquin River to the north and east and a 100-year levee <br /> of Reclamation District No. 2095 to the west. Egress and ingress is by a 20-ft wide private road i <br /> from the levee. <br /> k _ 1 <br /> t. va�ey AB research <br />
